    Product feature
    1. Easy Fit
      The Easy Fit system allows you to adjust your ski helmet to your body shape, thanks to a dial at the back of the helmet retained by elastics. This retention system can be adjusted precisely and remembers the position of the helmet on your head.
    2. Full Earpad
      The Full Earpad is an ear design that offers better support, more warmth and therefore more comfortable to use. The two earpieces are made of a single textile piece, thus forming a contour around the neck.
    3. Air Cooling
      Air Cooling is a system that directs the air in order to eliminate the heat and moisture from your ski helmet. This helmet has 12 air vents for keeping you comfortable at all times.
    4. Hard Shell Construction
      The Hard Shell Construction makes your helmet more durable and robust. This type of structure has an injection-moulded ABS shell that can withstand powerful impacts. It is both durable and can withstand significant bumps and knocks. The internal EPS lining absorbs the shockwave in the event of a collision. We advise you to replace your helmet at least every 5 years unless it gets damaged by a significant shock in the meantime.
    5. Compatibility with prescription glasses
      Everyone, including those who wear glasses, should be able to enjoy skiing. Wed'ze therefore offers a helmet with a visor that is more practical to use than OTG ("over the glasses") ski goggles. However, some models of glasses are incompatible on account of their size. We recommend visiting your local Decathlon store to try the helmet on with your glasses.
    6. Cold barrier
      The Cold Barrier provides a genuine thermal barrier protecting you from the cold when the liner hat's hem is folded down over your forehead.
    7. Removable textile
      The advantage of the removable liner is that it can be washed separately. The liner hat of this ski helmet is removable and machine washable at 30°C.
    8. S2 Visor Lens
      The visor offers 100% protection from ultraviolet rays. The tint of the visor, which allows between 22% and 40% of the light to pass through, is suitable for all types of weather conditions. The polycarbonate material is very resistant to impacts. However, it is not very resistant to scratching: We therefore recommend protecting your visor by placing it in its bag after each use.
    9. EN 1077 standard
      The EN 1077 standard is a European standard that applies to helmets used for skull protection when downhill skiing or snowboarding. A feature of this standard are the tests undertaken to check the shock absorption properties and the resistance to penetration.
    10. After-sales service
      Some STREAM 550 S2 helmet parts are available as part of our after-sales service from our in-store workshops. Available parts: the original S3-type visor and the visor attachment kit (screws and spacers).
    11. EN 1077 STANDARD
      The EN 1077 standard is a European standard that applies to helmets used for skull protection when downhill skiing or snowboarding. This standard is based on the shock-absorbing capacity and penetration resistance, and is divided into 2 categories: A: Stiff ear helmet / B: Soft ear helmet.

    • Comfortable but defective

      Liz (United Kingdom)
      Used for 1 week or less
      I bought two of these helmets as they were so comfortable in the shop. The visor certainly provided better all round visibility however when wearing in snowy conditions we both found that there was a gap at the top of the visor which let water run don between it and the helmet then promptly froze on the inside which was impossible to clear. This made visibility zero which in the poor conditions was very frightening. I would go as far as to say the helmet is not fit for purpose!

      We met a French family whilst skiing who's son had found the same problem and had removed the visor and was using goggles instead held on with "duck tape".
      Disappointed in the lack of response from Decathlon in spite of several emails to Customer Services and being promised that the National Sports Manager fro Ski would be in contact.
      Really disappointed as we are loyal and regular customers of Decathlon...shame
      Response of the brand
      Dear Mrs. Morgan,

      Thank you for getting in touch, and my apologies for the inconvenience caused by the helmets you purchased. This is the first instance I've heard of such a problem on this helmet. The gap should be filled out with a small layer of foam normally. 

      Would you be so kind as to get in touch with our customer loyalty team to get the helmets shipped to me? It'd be helpful to see if there was a defect on the helmets. They'll be able to assist you in this process.

      Thank you,

    • Very comfortable for spectacle wearers

      Keith (United Kingdom)
      Used for 2 to 8 weeks
      I have used this helmet for 3 ski trips now and found it much better than goggles when wearing my normal glasses. I have previously used OTG goggles but having a visor is definitely better. The field of visibility is much better. I found that the foam ventilation inserts effectively prevented misting.

      In poor weather the S2 visor does cut out a lot of light but there is an option for a yellow visor to be bought separately.
      Looks good, great visibility
      None really
    • Perfect starter helmet

      Stephen (United Kingdom)
      Used for 2 to 8 weeks
      I got this for my first week's skiing having read it would work well when wearing glasses. At first I thought the visibility was quite poor until my friend pointed out I had yet to remove the protective film on the inside of the visor!! So don't forget to do that as there is no label or text to warn you! Once that was off, it worked great, and I had all kinds of conditions from sunny to heavy snow and fog. I did find my glasses would still steam up sometimes - there is a layer of foam under the visor to create a seal which I think contributes to this. I ripped out the foam and had no problems with steaming up after that, you obviously get a bit of cold air circulating around your eyes but I don't mind that. Overall it's a very comfortable helmet, pretty light but feels sturdy. Interchangeable visors would obviously be good if Decathlon could get those on the site. Note I had to go up one size from normal expected measurements as it was too tight.
      Great for glasses, light, comfortable
      Still steams up with the foam
    • Excellent helmet

      Sarah (United Kingdom)
      Used for 1 week or less
      The helmet is very comfortable with padding to cover up the fastening strap for added comfort. The fasten itself is very easy to undo and do up with gloves on as it is very strong magnetic, but there is no chance of it falling off during wear. When the visor is down, it does not restrict any sight from either side. The visor is perfect as it moves up and down with ease whenever necessary and it also has room for sunglasses underneath. I have used this helmet all week skiing and felt very protected!
      Warm, comfortable, wide vision, easy use.
